Question

grade 10 Physics ( refaction lab)

What you will do 1. Centre your protractor where Indicated on the diagram sheet with the curved edge pointing to the LEFT of the page. Starting from the bottom end of the vertical line (the normal), mark off angles of 10, 20, 30, 40, 50, and 60. 2. Remove the protractor and centre the acrylic block on the same spot of the paper. Ensure that the curved side is pointing to the TOP of the page. 3. Project a single ray of light at the centre of the flat edge of the block at an angle of incidence of O* (that is, you will be projecting along the normal). Mark the path of the incident AND refracted light rays with a pencil. Write "0"" next to the refracted ray to remind yourself which incident ray it corresponds to. 4. Repeat step 4 for angles of incidence (zi) of 10, 20, 30, 40, 50, and 60°. You already marked where these are on the page, so you know where to aim your ray box! Remember to write which Incident ray corresponds to which refracted ray. 5. Remove the block and measure the angles of refraction (2R) for the 7 light rays that you aimed at the block using your protractor. Remember that the angle of refraction is measured from the normal to the refracted ray. Record these on your lab-sheet in the observation table. 6. Calculate the remaining columns in your observation table and answer the questions (on the back and next page). Observation Table Angle of Incidence in air (21) Angle of refracted ray in acrylic block 21+2R sin zi sin R (sin zi) + (sin R) (ZR) 0° 101 20⁰ 301 40 50⁰ 60"
